STOVE.

Patented Aug. 14,1906;

Application filed July 14, 1904. Serial No. 216,472.

and exact description of the same, reference being had to theaccompanying drawings, forming apart of this specification, and to thereference-numerals marked thereon.

My present invention relates to improvementsin stoves; and it has forits object to provide a device of this character wherein the rate andits supporting-frame maybe bodi y withdrawn laterally from beneath thefire-pot of the stove and out upon the hearth thereof for the purposesof inspection or re newal and which when in operative positionwithin-the stove is held therein by a retaining device that may beeasily swung into position and locked to effectually retain the grate inits normal position beneath the firepot.

To these and other ends my invention consists in certain features ofconstruction and arrangement to be hereinafter more fully explained, andpointed out in the claims hereunto annexed.

In the drawings, Figure 1 is a fragmentary viewof a stove embodying mysaid invention, parts being broken awayfor clearnes s. Fig. 2 is asectional view thereof in the line 2 2, Fig. 1. Fig. 3 is a verticalsection on the line 3 3, Fig. 1. Fig. 4 is a side view of the stove withthe ash-pan in section, showing the outer door removed to expose thegrate-retaining device. Fig. 5 is asimilar view showing the.

outer door in its closed position. Fig. 6 is a vertical sectional viewon the line 6 6, Fig. 2. Fig. 7 is a horizontal sectional view similarto Fig.2, showing the side and front. doors and thegrate-retainingdevice in open position and the grate partially withdrawn from thestove; and Figs. 8 and 9 are fragmentary .viejws showing a modified formof retaining device.

The same numerals of reference designate corresponding parts in theseveral views.

In order that a clear understanding may be had of my saidinvention,reference will be had particularly. to that form thereof illustrated inFigs. 1 to 7 ,inclusive, of the drawings, wherein 1 designates thegrate-frame, which for the present purposes is preferably substantiallyrectangular, andat each end .of this frame are provided the lhangers -34, in which are journaled the revoluble grateebars 5 and 6, anextension2 being preferablyformed upon the journal of one of these grate-bars andprovided with a gear-Wheel? meshing with the wheel 8 uponthe journal ofthe opposite grate-bar to enable said bars to be convenientlyandsimultaneously rotated by the application of a crank or othersuitable implement at the exterior of the stove. This grate-frame issupported in the present instance by a pairof horizontally-arrangedsupports or ways 9 and 10, which are formed in the chamber immediatelybeneath-the permit the ready removal of the grate. is v formed.

When the grate is in its proper position .beneath the fire-box, it isretained therein by-a retaining device embodying in the present instancea swinging arm 13, hingedat one end by the hinge 14 to the stove at onesideof the side opening and carrying at itsopposite end the extension15, forming a closure. for the recess 12 and having a portion adapted toengage the operating extension 2 of the gratebar to prevent lateraldisplacement. A laterally projecting rib 16 is preferably formed uponthe inner side of this arm, which will engage the lateral edge of thegrateframe 1- to firmly retain it in position, suitable fasteningdevices 17 17 being-preferably employed for locking the grate-retainingarm 13 in its closed position. In practice. Ip'refer to locate the hinge14 at a point directly in rear of the recess 12 in the front of thestove, so that the retaining-arm 13 in swinging open will require aminimum .amount .of clearance, such an arrangement permitting the frontdoor 18 to be hinged comparatively close to the stove-body and stillclear. the lateral projection 15 upon the free endof the retainingdevice.

The lower portion of the retaining-arm 13 is preferably cut away for thepurpose of exposing the under side of the grate and rendering theash-pit beneath it accessible, andit is also preferable to fit thisretaining-arm into the side of the stove in such a manner as to presenta flush surface against which the draft-door 19 may snugly lit, thehingepins 20 20 upon this door cooperating with the hinge-lugs 21 21,which are located in the present instance on the stove at the side ofthe draft-opening and above the swinging arm 13, so as to clear thelatter in its motion. Beneath this draft-door is hinged the hearthplate22, which is adapted to fit within a correspondingly-shaped seat 23,formed in the upper surface of the hearth 24, said plate forming aclosure or cover for the overhanging normal position within the stovefor the purposes of inspection or repair, the draft-door 19 is removedfrom its hinges, and the hearthplate 22 is swung into its open position,thereby enabling the fastening device 17 to be manipulated to releasethe grate-retaining arm 13, permitting it to be swung on its hinges 14to withdraw the lateral extension 15 from the recesss 12 in the front ofthe "stove to allow the passage of the operating extension of the grateand also disengaging the laterally-proj ecting rib 1 6 from the lateraledge of the grateframe. When this has been accomplished, the grate maybe freely with drawn from the stove through the aperture thus uncovered,the overhanging ends of the grate-frame sliding upon the ways 9 and 10in the front and rear walls, respectively, of the grate-chamber.

Should it be found desirable to employ a sim ler form of grate-retainer,one similar to t at shown in Figs. 8 and 9 may be employed, in whichcase the retaining device 13 is provided with a pair of depending lugs29 29", the lower ends of which are forked or bifurcated to engage uponeach side of the portion 30 of the stove, the upper portion of theretaining device being provided with a laterally-projecting rib 16*,that will engage the lateral edge of the grate-frame when it is in itsnormal locked position, locking devices 17 being employed for retainingit in such a position. The forward end of this retaining device isprovided with an extension 81, the upper edge 32 of which is preferablyformed ter, causing the projecting rib 16 to disengage from the sideedge of the grate-frame and causing the extension 31 to be withdrawnfrom the correspondingly-shaped recess of the stove, thereby permittingthe grate to be freely withdrawn.

A draw-out grate embodying my invention is very simple and inexpensivein construction, and in operati on it provides an extremely convenientmeans by which the grate may be readily Withdrawn from the stove for thepurposes of inspection or repair. Moreover, it will be obvious that asthe grate is withdrawn laterally, so that it will rest above the hearthat the side of the stove, ashes and cinders dropping from the grate willbe received in the ash-pit, thereby avoiding those annoyances that areexperienced with drawout grates as heretofore constructed. It will alsobe obvious that a grate-retaining device embodying my invention may bereadily and easily unlocked and locked in position without liability ofbecoming lost or broken, and when in its locked position it willeffectually retain the grate in its proper position without obstructingthe draft or interfering with the functions and operation of otherportions of the stove.
